Does anyone here know the real history of the packer boot?

PACKER BOOTS

Packer Boots were originally worn by enlisted soldiers in the U.S. Army in the 1800's who would not make a career out of military service, but muster out of service in the west. The packer boot is suited for farm and ranch footwear, and was made for people in the Rocky Mountains working with packhorses (thus the name). Form and functionality make these boots the preference of outdoorsman everywhere.These are lace-up boots, and are usually 10" high, but fasion packers can be taller, as high as the knee. They have a kilty (false tongue) and are made of very durable, thick leather. Most packer boots are brown, but they are also available in black and other colors. They usually have rubber, neoprene, or sometimes Vibram® soles.

Is that right?

History

In the mid-1800s, the most popular boot in America was the Wellington, a leather military-type, pull-on boot that was worn by many Civil War officers. Unfortunately, these boots did not hold up well over time, so most enlisted men, who were primarily farmers, wore boots that laced up and served them well on the farm. After the war, shoemakers began to make early cowboy boots of waxed leather and added the Cuban angled heel that horsemen preferred. Frontiersmen had long preferred lace-up boots, so the angled heel was added to the lace-up style, forming what is known as the "packer boot," the style favored by ranch hands.

Then there is the packer.  As was mentioned, the lace-up was common on the American frontier. Enlisted men were less likely to be career men and often mustered out of the service in the west. There are the historical photographs of cowboys sitting on the top rail of the corral watching a hand ride out a bronc. In not a few of these photographs the men wearing lace-ups outnumber the men wearing traditional western boots. Hyer Boot Company, in their 1926 catalogue offers at least three pages of lace-up styles--for the ranch hand 

Can anyone expand on this?
